Any idea where I would be able to find just the brackets if I were to install on an 09+?

if you have a 06-08 f-sport rear sway bar kit, and you have a 09-11's model. you will need rear sway bar 4x bolts #90119-A0169 and 2x rear sway bar brackets #48832-30060. you can get both parts at your lexus' dealership.
